Depending on the applicable legislation and the unit's maximum working pressure
(see "PS High" on the unit name plate), larger piping thickness might be required.
5.3.2 Refrigerant piping insulation
▪ Use polyethylene foam as insulation material:
- with a heat transfer rate between 0.041 and 0.052 W/mK (0.035 and
0.045kcal/mh°C)
- with a heat resistance of at least 120°C
▪ Insulation thickness

If the temperature is higher than 30°C and the humidity is higher than RH80%, the
thickness of the insulation materials should be at least 20 mm to prevent
condensation on the surface of the insulation.
